New York Attorney General Letitia James has filed the state’s first lawsuits under a new rent stabilization compliance law, and the two Brooklyn landlords named as test cases give a preview of how aggressively the office intends to police thousands of rent-stabilized buildings going forward.
Two landlords, two very different kinds of trouble
The first lawsuit targets John Anderson, owner of 1075 Dean Street in Brooklyn, who according to the Attorney General’s office failed to provide a single tenant a proper rent-stabilized lease for ten years. When that tenant eventually pushed back and requested the lease she was legally owed, the complaint alleges Anderson retaliated by cutting off her gas, water, and electricity. The filing also accuses him of falsifying the building’s status on a New York City Department of Buildings application and, in a detail that stands out even by landlord-tenant dispute standards, sending an impostor to impersonate him during court proceedings related to the case.
The second lawsuit involves Claudette Henry, owner of 134 Sackman Street, who the complaint says never registered her building with New York State Homes and Community Renewal at all and separately attempted illegal evictions against tenants living there. Henry ranked eighth on the Public Advocate’s list of the city’s worst landlords in 2025, and the Attorney General’s office says she ignored repeated compliance communications from investigators before the lawsuit was filed.

What the new law actually requires
New York’s rent stabilization compliance law, which took effect this year, requires landlords of stabilized units to register the legal regulated rent with state housing regulators, issue tenants leases that reflect their actual stabilized status, notify tenants in writing of their rights under the law, and provide the Attorney General’s office with a sworn certification confirming they’ve done all of it. It’s a paperwork-heavy requirement on its face, but the intent is straightforward: tenants can’t enforce rent protections they don’t know they have, and a landlord who simply never registers a unit can keep charging market rent on an apartment that’s legally supposed to be capped.
The penalties the Attorney General is seeking reflect how the office wants this enforced. Beyond forcing both landlords to register their units and issue proper leases, the lawsuits seek restitution for any rent tenants were overcharged, with 9% interest tacked on. Civil penalties for harassment run from $2,000 to $10,000 per affected tenant, and buildings that remain unregistered face an additional $500 per unit, per month, for every month they stay out of compliance. For a landlord sitting on a multi-unit building for years without registering, that monthly penalty alone can add up faster than most rent rolls.
Why these two cases were picked first
Choosing a landlord accused of cutting off utilities and sending an impostor to court, alongside one already publicly named among the city’s worst, is not a subtle move. Attorney General James said in the announcement that rent stabilization and tenant protection laws exist to help keep working New Yorkers in homes they can afford, and that her office will not shy away from taking immediate action against any landlord who fails to follow the law or attempts to overcharge or illegally evict tenants.
Tenant advocates have pushed for years for a compliance mechanism with real teeth, arguing that registration requirements without enforcement just become one more rule landlords quietly ignore. These two lawsuits are the first real test of whether the new law changes that calculation. If the cases hold up in court, they’ll set the terms other rent-stabilized landlords across the city are likely to measure their own paperwork against, whether they’re following the letter of the law already or hoping nobody checks.
Thousands of buildings are watching how this plays out
New York City has hundreds of thousands of rent-stabilized units spread across tens of thousands of buildings, and enforcement of tenant protection laws has historically depended on individual renters knowing their rights well enough to file a complaint in the first place. A registration requirement backed by sworn certifications shifts some of that burden onto landlords directly, since it forces an affirmative filing rather than waiting for a tenant to notice something is wrong. Housing attorneys who work with tenants have noted that unregistered units are often the ones where renters have the least idea what protections they’re actually owed, which is part of why regulators picked buildings with documented harassment and eviction attempts as the law’s first test cases rather than a landlord with a purely paperwork-only violation.
The two lawsuits also arrive at a moment when the Public Advocate’s worst-landlords list and similar tenant-tracking efforts have made it easier for the Attorney General’s office to identify repeat offenders before a formal complaint even lands on a desk. Whether that translates into a wave of similar filings against other landlords, or whether these two cases remain the exception rather than the start of a pattern, will likely depend on how quickly the courts move and how much restitution tenants in these buildings actually recover.
